The Gambino representative in Baltimore was Frank Corbi,
he was the most recent Gambino capo there (that I'm currently aware of). He was involved in starting a chain of pizza restaurants that his descendants continue to run - through his grandson and grandnephew. His older brother Pasquale was the previous capo in charge from the 20s until his death in 1955. Frank Corbi is deceased (I beleive).
I was once told by a semi-retired wiseguy from New Jersey that Baltimore was always too rough (he meant full of african-americans) to be completely taken over by the italians. FWIW
